The poll found that 91 percent of Democrats, 65 percent of Independents and a high of 37 percent of Republicans view Clinton favorably. The poll comes on the day Clinton testified before House and Senate committees on the September terrorist attack in Benghazi, Libya.

She is also seen favorably by a majority of all ideological groups, including 49 percent of conservatives. An astounding 79 percent of self-identified moderates also said they viewed her favorably.

The poll also showed that Clinton is in a much better position for a theoretical 2016 run for president than current Vice President Joe Biden. Clinton is viewed favorably by a 67-26 split. Biden, meanwhile, was viewed favorably by just 48 percent of respondents and unfavorably by 37 percent.
